The updated Porsche Cayman GT4 may soon make its debut as seen in this latest batch of spy photos. Our eagle-eyed spies spotted this 718 Cayman GT4 undergoing cold weather tests while completely undisguised. In fact, only the snow is hiding more specific details of the upcoming GT4.

Compared to the last time we spotted the GT4, the prototype seen here appears almost production ready. As mentioned early, there seems to be a lack of camouflage or false panels attached to this test mule. In fact, Porsche didn’t even bother to cover their badges.

In front, there is a revised bumper with larger intake vents which channel air to what appears to be coolers. Right above the side intakes appear to be LED day-time running lights which double as turn signals. Moving to the back, a large chunk of snow hides most of the revision to the rear bumper and diffuser. Keen eyed readers however would notice that there is a new split design exhaust. Completing the GT4 makeover is a fixed rear wing.

Powering the 718 Cayman GT4 is said to be a detuned version of the 4.0-liter flat six found on the 911 GT3. In comparison, the 991.2 GT3 produces 500 PS and is available with either a manual or PDK transmission. It is still uncertain how much power the upcoming 718 Cayman GT4 will produce.

Given the lack of camouflage on this prototype, it is possible that Porsche might debut the 718 Cayman GT4 soon, possibly at the upcoming Geneva International Motor Show this March.
